Connecting the SRX550 HM to External Devices

 

Connecting the Modem to the Console Port on the SRX550 High Memory Services Gateway

To connect the dial-up modem to the console port on the SRX550 High Memory Services Gateway:

  1. Turn off power to the services gateway.
  2. Turn off power to the modem.
  3. Plug one end of the Ethernet cable into the console port on the services gateway. (Figure 1 shows the console cable connector).

  4. Plug the other end of the Ethernet cable into the RJ-45 to DB-9 serial port adapter. Note

    Most modems have an RS-232 DB-25 connector. You must separately purchase an adapter to connect your modem to the RJ-45 to DB-9 adapter and Ethernet cable.

  5. Connect the serial port adapter to a separately purchased DB-9 socket to DB-25 plug adapter or other adapter appropriate for your modem.
  6. Plug the modem adapter into the DB-25 connector on the modem.
  7. Connect the modem to your telephone network.
  8. Turn on the power to the modem.
  9. Power on the services gateway by pressing the Power button on the front of the services gateway. Verify that the POWER LED on the front panel turns green.

Connecting to the SRX550 High Memory Services Gateway from the CLI with the USB Console Port

You can connect your management station to the USB console port on the services gateway and use the CLI to configure the services gateway, as shown in Figure 2.

To connect to the CLI using a local management device through the USB console port on the services gateway:

  1. If you have not already done so, install the USB console driver software.

    Download the USB driver to the management device from the Downloads page. To download the driver for Windows OS, select 6.5 from the Version drop-down list. To download the driver for macOS, select 4.10 from the Version drop-down list.

    Caution

    Install the USB console driver software before attempting to establish a physical connection between the services gateway and the management device, otherwise the connection will fail.

  2. Plug the large end of the USB cable supplied with the services gateway into a USB port on the management device (see Figure 2).
  3. Connect the other end of the USB cable to the USB console port on the services gateway (see Figure 2).
  4. Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal), and select the new COM port installed by the USB Console driver software. In most cases, this is the highest-numbered COM port in the selection menu.
  5. Configure the port settings, as shown in Table 1.

  6. If you have not already done so, power on the services gateway by pressing the Power button on the front of the services gateway. Verify that the POWER LED on the front panel turns green.

    The terminal emulation screen on your management device displays the startup sequence. When the services gateway has finished starting up, a login prompt appears.

  7. Log in as the user root. No password is required at initial connection, but you must assign a root password before committing any configuration settings.

Connecting the CLI at the User End for the SRX550 High Memory Services Gateway

To connect to the CLI through a dial-up modem connected to the console port on the SRX550 High Memory Services Gateway:

  1. Connect a modem at your remote location to a management device.
  2. Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal) on the management device.
  3. Select the COM port to which the modem is connected (for example, COM1).
  4. Configure the port settings shown in Table 2.

  5. In the HyperTerminal window, type AT.

    For more information on the AT commands, see the Installation and Upgrade Guide for Security Devices.

    An OK response indicates that the modem can communicate successfully with the COM port on the management device.

  6. To dial the modem that is connected to the console port on the services gateway, type ATDT remote-modem-number. For example, if the phone number of the modem connected to the console port on the services gateway is 0019785551234, type ATDT 0019785551234.

    The services gateway login prompt appears.

  7. Log in as the user root. No password is required at initial connection, but you must assign a root password before you commit any configuration settings.

Configuring the Modem at the SRX550 High Memory Services Gateway End

Before you can connect a dial-up modem to the console port on the SRX550 High Memory Services Gateway, you must configure the modem to accept a call on the first ring and to accept DTR signals. You must also disable flow control on the modem.

Note

These instructions use Hayes-compatible modem commands to configure the modem. If your modem is not Hayes-compatible, refer to the documentation for your modem and enter equivalent modem commands.

To configure the modem on the services gateway end:

  1. Connect the modem to the management device (a desktop or laptop computer).
  2. Power on the modem.
  3. From the management device, start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal), and select the COM port to which the modem is connected (for example, COM1).
  4. Configure the port settings, as shown in Table 3.

  5. In the HyperTerminal window, type AT.

    For more information on the AT commands, see the Initial Configuration for Security Devices.

    An OK response verifies that the modem can communicate successfully with the COM port on the management device.

  6. To configure the modem to answer a call on the first ring, type ATS0=1.
  7. To configure the modem to accept modem control DTR signals, type AT&D1.
  8. To disable flow control, type AT&K0.
  9. To save modem settings, type AT&W.
